| abstract |
The invention relates to a high-frequency weldable and cold-flexible polymer mixture comprising a copolymer of ethylene with a polar comonomer, selected from the group of vinyl esters of saturated C¶2¶-C¶8¶-carboxylic acids, the C¶1¶-C¶12¶ Alkyl acrylates and / or methacrylates, where the comonomer content is below about 25% by weight, a terpolymer and / or copolymer of ethylene, popylene and / or butylene and a polar comonomer, the comonomer content being above about 25% by weight , as well as a thermoplastic polyolefin. The invention also relates to a film or a shaped body containing the polymer mixture according to the invention, and to the use thereof. The teaching according to the invention simultaneously provides high flexibility at low temperatures and good heat stability with sufficient high-frequency weldability and good weld seam strength. |
